Our information shows a p0054 code as heated oxygen sensor bank 1 sensor 2. Heater circuit. Should be the second O2 sensor from the engine. If you unplug it you should be able to measure resistance across the two wires that are the same colour and compare to the other sensor. You will most likely find an open circuit across those heater wires. So the sensor will need to be replaced.
